No overload is permitted on these ratings. The generator is peak rated (as defined in ISO8528-3). Prime Applicable for supplying continuous electrical power (at variable load) in lieu of commercially purchased power. There is no limitation to the annual hours of operation and the generator set can supply 10 percent overload power for 1 hour in 12 hours. LEHE5123-02 4
